Frandom

From the frandom page:
"The frandom suite comes as a Linux kernel module for several kernels, or a kernel patch for 2.4.22. It implements a random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom."

Does frandom generate good random numbers? For anything not related to cryptography the answer is probably "yes". Don't use frandom for cryptographic purposes though, as it internally uses the dated and vulnerable RC4 algorithm.

Beneath in the example section, you'll find 'real', 'user' and 'sys' information, what they mean you can find here.

To use frandom to wipe a disk without encrypting it afterwards (for example for the simple destruction of data (even though overwriting the disk with /dev/zero would be sufficient and faster in this case)), use the dd command:
